List: The six best TV guest appearances by rock stars

Katy Perry, coming to a sitcom near you.

The news that Katy Perry would be guest-starring on "How I Met Your Mother," following in the footsteps of Britney Spears, who was tentative and adorable on her own "HIMYM" stint, got Click Track thinking about other recent pop star TV cameos.

We ranked some of our recent favorites, with some caveats: "The Simpsons," which deserves kudos for featuring every act ever, of all time, doesn't count. Nor do golden oldies like that episode of "The Brady Bunch" with the Monkees' Davy Jones, which is every bit as awesome as you remember it.

Some of our other favorites, ranked in order of implausibility (leave yours in the comments):

6. Chris Daughtry on "CSI: NY"

It turns out Daughtry is as annoying on TV as he appears to be in life.

5.Sebastian Bach on "Gilmore Girls"

Bach had a recurring role as a musician in Lane's band. He was cheery and very tall. Other than that, we don't remember much about this. Sadly, Bach's role overshadowed that of the other musical regular, Grant-Lee Phillips, who played a wandering minstrel throughout most of the show's run.

(Dylan, Dharma and other things we can never unsee, after the jump.)

4. Boy George on "The A-Team"

This happened!

3. Warren Zevon on "Suddenly Susan"

He had great timing, which isn't surprising. And Rick Springfield was there, too.

2. Kid Cudi on "One Tree Hill"

Poor Cudi. This was the '00s equivalent of the Flaming Lips playing the Peach Pit on "Beverly Hills 90210." Except Wayne Coyne didn't have to give an inspirational pep talk at the end.

1. Bob Dylan on "Dharma and Greg"

We have no idea why this exists. Yet we must accept the fact that it does. Also slumming it: T Bone Burnett (in sunglasses, at eleven o'clock).
